[PATCH] uml: Fix SIGWINCH relaying
This makes SIGWINCH work again, and fixes a couple of SIGWINCH-associated
crashes. First, the sigio thread disables SIGWINCH because all hell breaks
loose if it ever gets one and tries to call the signal handling code. Second,
there was a problem with deferencing tty structs after they were freed. The
SIGWINCH support for a tty wasn't being turned off or freed after the tty went
away.
